Dynamic Manipulation of Infrared Radiation with MEMS Metamaterials
An electrically tunable MEMS metamaterial that effectively manipulates radiation in the mid-infrared wavelength range is experimentally demonstrated. The metamaterial consists of an array of suspended metal-dielectric elements above a metal ground plane on a carrier substrate. A voltage applied between the metallic metamaterial array and the bottom ground plane layer permits adjustment of the distance between them, thus greatly altering the electromagnetic properties. © 2013 WILEY-VCH Verlag GmbH & Co.
